change(esp_timer): esp_timer_init_os now returns ESP_OK if already initialized

Browse Source 
Previously it would return ESP_ERR_INVALID_STATE, which meant that if called from
user-code before the system tries to initialize the timer then esp-idf would
fail to boot.

This could happen if a user wanted to use esp-timer from a cpp constructor.
